Is sharing phone chargers bad? (Solved)

Have you ever been in a situation where you desperately need to charge your phone but you don’t have your charger with you? But your friend is kind enough to share his charger with you.

Or you are sharing your room with someone and your roommate often uses your charger or you both share one charger. Now you are wondering is it okay for us to share a charger or use 1 charger on different phones.

There’s been a lot of debate lately about whether or not it’s safe to share a phone charger. Some people believe that sharing a charger can be dangerous and that it can transfer viruses or something.

But is this true is sharing phone chargers really bad?

Nope. All chargers have the same function. If you have a good charger with a rated capacity(Amperage) greater than the Phone needs with overload protection, it will work fine.

In this article, we will explain what are some of the things that you need to keep in mind if you are sharing a charger with someone and can it transfer virus.


Even though it is perfectly fine to use a different charge on your phone but you have to see if the charger meets the requirements especially if you use the same charger every day.

There is a reason why most of the devices come with their charger. The charger is specific to that device and it delivers the perfect amount of power and current that the phone requires.


All devices have a certain voltage limit. Going over the voltage limit can damage your phone. Most of the charger in the market has a standard voltage of around 5 volts. So, if you use a charger with the same voltage, it won’t damage your phone.

But there are some chargers with a higher voltage limit and if you use that charger, it can damage your phone over time if the voltage is a bit higher.

So, before using a charger, check the voltage limit. If the charger is within the voltage limit, it is safe to use.

However, if the charger has a higher voltage, it is not safe it can damage the charging port.


Have you noticed that if you are using a third-party charger it is taking a long time to charge than it usually does or you use a different charger and your phone charges quickly?

This happens if the amount of amperage supplied by the charger is less than what the phone needs or trying to pull.

This can be damaging to the power supply as well as the device because the phone will try to pull more amp than what the charger can provide.

Make sure to check the amperage rating of the charger to see if it meets the requirements of your phone. And don’t worry about high amperage using a charger with high amperage is perfectly fine.

Modern devices are made to regulate the amount of amperage entering a battery. So, the phone will only take as much amperage as it needs.

Is it bad to let people use your charger?

It is not bad to let people use your charger as long as the charger is of good quality and meets the requirements of their phone.

Many people believe that it is bad to let other people use their phone chargers because it could cause the phone to overheat and potentially damage the battery.

Most phones have safety features that will prevent this from happening. So even if the charger is not supplying optimal power for the phone one time use will not have any major effect.

Another concern is that people might accidentally damage your charger. This is a valid concern, but it is also one that is easily mitigated by asking the person to be careful with it.

Can you get a virus from sharing chargers?

The short answer is no. You cannot get a virus from sharing chargers. A computer virus needed some type of storage unit.

A charger does not have any type of storage or any type of program that can execute a virus and transfer it. So, it is not possible to get a virus from sharing chargers.

There are some other ways you can get malware on your phone but sharing a charger is not one of them.

So, In theory, it is perfectly fine to share a charger or use some else charger if it was a one-time thing but if you are using it on daily basis.

It will be a safe practice to check the voltage limit and amperage rating of the charger. So that you don’t have to worry about damaging your phone’s battery.
